Embodiment Construction

[0028] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0029] Due to the lack of resistive loss and the characteristics of strong magnetic field, industrial superconducting magnet products are becoming more and more mature, and the amount of use is also increasing. During the operation of superconducting magnets, the following problems will be faced.

[0030] (1) Due to the particularity of superconducting materials, superconducting magnets operate in a strict low-temperature environment. Due to various disturbances during stable operation, superconducting magnets will undergo quenching. In severe cases, quenching inside the magnet will cause The local overheating of the superconducting coil may cause excessive thermal stress or burn the insulation, causing irreversible damage to the ...
